OKLAHOMA CITY – Second-seeded Oklahoma posted a 5-2 win over No. 7 Texas Tech in the final opening-day game of the Phillips 66 Big 12 Baseball Championship on Wednesday evening at AT&T Bricktown Ballpark.

Andrew Doyle (8-4) picked up the win for Oklahoma, scattering four hits in eight innings of work. Doyle also struck out four, walked one and had two unearned runs, while tossing an efficient 101 pitches. Closer Ryan Duke pitched a scoreless 1-2-3 inning in the ninth to earn his 15th save, and Texas Tech’s AJ Ramos dropped to 5-5 on the season with the loss.

OU’s Casey Johnson was 2-for-4 with a pair of runs scored, and Ross Hubbard was 2-for-4 with a career-high-tying four RBI to lead the Sooners.

Oklahoma and Texas Tech managed just one hit apiece through a quiet first three innings, but Chris Richburg sparked a two-run effort for TTU in the top of the fourth. His single up the middle brought Joey Kenworthy across the plate, and Richburg then advanced to second on a throwing error and added his own run to up the lead to 2-0. The senior boasts a team-best hitting streak of nine games after his 1-for-4 night.

The Sooners were quick to answer, however, as they produced a pair of runs for a two-out rally in the bottom half of the inning. Casey Johnson and Garrett Buechele produced back-to-back singles, followed by a base-clearing triple by Hubbard past a diving Kengray Fleming in centerfield to plate both runners and tie the game at 2-2.

In the bottom of the fifth inning, OU tacked on another run from Jamie Johnson, who scored on a groundout by Bryant Hernandez. The Sooners added another pair of scores on a single by Hubbard to bring in Casey Johnson and Aaron Baker.

The bottom of the eighth saw the Sooners have another chance to score with two runners on and one out. Matt Harughty grounded into a double play between Kenworthy and Willie Rueda to halt the inning and send the game to the top of the ninth. But Oklahoma dashed any hope of a Tech rally, retiring three straight batters. Duke capped the effort by getting the final two Red Raider batters on swinging strikes.

Texas Tech moves on to third-seeded Missouri at 3 p.m. on Friday, while Oklahoma continues pool play with No. 6 Texas A&M on Friday at 7:30 p.m.
